FIREARM Original Filed Aug. 20, 1935 Patented May 17, 1938 UNTED STATES FIREARM pany of Germany Original application August 20, 1935, Serial No. 37,078. Divided and this application August 24, 1937, Serial No. 160,680. In Germany May 6 Claims. (Cl. 42-1) This invention relates to rearms, and particularly to automatic pistols with hammer and trigger.

It is an object of the invention to provide an improved magazine holder which, as Vknown per se, cooperates with the push rod for the hammer. To this effect the push rod, the hammer spring and the magazine holderare combined into a unit, the insertion and removal of which are thus simplified, and the unit cannot be placed in a wrong position.

A further object of the invention is to provide a device for holding the magazine for pistols, whose shape is adapted to the shape of the pistol, and does not expose any openings in its active and inactive positions, and further notwithstanding all the foregoing is simple, safe and easily manipulated.

The invention will now be more fully described in connection with the drawing of which,

Fig. l is a longitudinal section of the rearmost part of a pistol stock with the magazine holder,

Vthe hammer spring and the hammer,

Fig. 2 is an elevation showing the magazine holder with the push rod and the hammer spring disassembled,

Fig. 3 is a section on the line A-B of Fig. 2, and

Fig. 4 is a section on the line C-D of Fig. 3.

|5| is the magazine holder which is placed in the stock of the pistol and supports the magazine 85. |58 is the push rod, |28 is the hammer sprin-g on the push rod, and |59 is the head of the push rod with which the hammer is connected as indicated in Fig. l. 'Ihe lower end of the push rod |58 has lateral projections |50 which are introduced through notches in the holder when it is desired to connect the parts of the unit. It will be understood that the projections |50 are not in active position when the unit is inserted in the pistol, and the spring |20 is compressed, as shown in Fig. l. Relative rotation of the parts is prevented in this position by an edge |56 of the magazine 85 which engages in a seat of the magazine holder |5I. lhen the unit is removed, the spring expands, and the projections |58 hold the push rod |58 against turning, by engaging in notches |511 at the top of the central cavity |53 of the holder, and against abutments |55 formed by such notches, so that the push rod is not forced olf by its spring |28.

To extract the unit, the side wall of the pistol stock is removed, the holder is disengaged from the edge |56 of the magazine, and the push rod, the hammer spring and the holder are extracted tions |50 have passed the notches |54 in the holder. The rod is now turned through 90, and extracted upwardly while the spring |26 expands.

By making the bayonet joint one-sided, for instance,- by making its two projections |50 of different size, the parts of the unit will fit only in one definite position with respect to each other. Since they are held against relative rotation when assembled, the unit will always t in the proper position.

'I'he push rod |58 and its head |59, and the projections |50, are preferably forged in one piece, so that the manufacture thereof is facilitated and cheapened.

Furthermore the magazine holder |5| has a notched lug |16 which bears on an edge |77 at the upper end of the edge member 58 which, as described, is secured to the magazine 85. The spring |25 which is under initial tension, bears on the top I'IB of the magazine holder l5! and turns the holder about its edge bearing llt, lll until a lug 8| at the lower end of the holder engages in a recess |82 in the magazine wall. The leverage at which the strong hammer spring |25 acts, is large compared with the leverage of the magazine 85 at the lug |8I, and therefore the magazine is rmly forced into the stock, and held in position.

The lower face of the magazine holder |5| is grooved at 85. To extract the magazine 85, pressure (in an inwardly inclined direction is exerted against the holder by its grooves. The holder |5| rocks about its edge bearing |16, and the lug |8| is extracted from the notch |82 of the magazine whereupon the magazine can be fully extracted. The rocking movement of the holder |5| is limited by an abutment |81 in the stock so that the holder will not jump from its edge bearing |15,

An important advantage of the magazine holder |5| according to my invention is that it closes the recess in which it is positioned, when the magazine 85 is inserted, and when it is extracted, so that access of dirt to the recess, to the cock spring |26, and to the push rod |58 is prevented. This is effected by the lug ISI at one side of the holder engaging in the recess |82 of the magan zine bottom at one side of the holder, and a strip |90 at its other side, which co-operates with a guard |9| of the stock. The lower end of the magazine holder is flush with the bottom of the magazine and the under side of the stock and thus does not interfere with the manipulation of the pistol, as in the 01d pistols.

The present application is a division of applicants co-pendng application, Serial No. 37,078, filed August 20, 1935.

What I claim is:

1. In a rearm having a magazine, a stock and a hammer; an operating rod for the hammer, said rod being enclosed in a cavity in the stock, a magazine lock in the base of the cavity for retaining a magazine in the stock, a bayonet joint connection between the magazine lock and the hammer operating rod, and means for re' movably securing the magazine lock in the stock. 2. In a rearm according to claim 1., in which two diierent lugs are provided on the operating rod for the bayonet joint to enable the rod to be assembled With the magazine lock in one position only.

3. In a firearm having a magazine, a stock and a hammer; an operating rod for the hammer, said rod being enclosed in a cavity in the stock, a magazine lock in the base of the cavity for retaining a magazine in the stock, a bayonet joint connection between the magazine lock and the hammer operating rod, means for removably securing the magazine lock in the stock,` a hammer operating spring abutting between the rod and the magazine lock, said spring biassing the lock into magazine retaining position, and a bearing in the cavity of the stock for securing the magazine lock in the stock with freedom to tilt about said bearing to retain and release the magazine.

4. In a firearm according to claim 3, in which the spring acts on the magazine lock with a greater leverage than that of the magazine about the bearing axis.

5. In a rearm having a magazine, a stock, and a hammer; an operating rod for the ham mer, said rod being enclosed in a cavity in the stock, a. magazine lock in the base of the cavity for retaining a magazine in the stock, a bayonet joint connection between the magazine lock and the hammer operating rod, means for Yremovably securing the magazine lock in the stock, a hammer operating spring abutting between the rod and the magazine lock, said spring biassing the lock into magazine retaining position, and a knife edge bearing in the cavity of the stock for securing the magazine lock in the stock With freedom to tilt about said knife edge bearing to retain and release the magazine.

6. In a firearm according to claim 3, in which the magazine lock closes the bottom of the cavity and is flush With the adjacent external surface of the stock.
